Does anyone have any advice on how to connect my Roland GR-55 guitar synth to Studio One 3?

I'm a newbie and was able to easily connect an Akai MPK mini but cannot figure out how to connect the guitar synth by adding it as an external device (the way I did for the Akai keyboard). For my Akai, I connected the USB out on the keyboard to a USB slot on my PC.

Do I need a different connection for my guitar synth like using an audiobox or something in between my guitar synth and my PC?

I was able to record the midi output of the GR-33 and it sounded good as long as I sent it back to the GR-33, maybe the 55 is like that. That can be good for recording a solo but if you didn't hold the note long enough, you can go in and edit that in midi and make it last longer etc.

Getting other synths to sound that good not so easy. It can be usable for some things but requires lot of effort of the guitarist to play perfectly and not have anomalies.

I've had a GR-50 since they came out (God, I paid $1200 for that thing). It works great through my MIDI ports of a MOTU patchbay, then into a Presonus Audio box. The audio outs of the GR50 into the audio inputs of the interface. The MIDI and audio naturally separate. With the GK-2 tracking, I have on my Fender Strat (54' Vintage), it tracks pretty well, but the real latency comes from the GK-2, due to the sheer physics of when a plucked string becomes enough of a stable frequency to read pitch. That's about 8-12 milliseconds. No matter what sensitivity the GR-50 is set to. It's always been a black eye of MIDI recording through a guitar (then, and largely now). Especially when playing anything staccato, like a tight bass line. The GK-3 I hear was a tad faster for reading pitch, but nothing to brag about. Still, you should have no issues hooking up your GR55 through your interface, if it has MIDI, and the interface is equipped with some respectable monitoring bypass.

As for the audio out of the GR, you should not have any delay, other that the normal through an audio interface latency, you would experience from that interface and internal mixer path.

You'll need some sort of Midi interface with a DIN five pin connector. I have a Casio MG-510 Midi guitar that I connect using a Roland UM-1G Midi interface. That interface is now discontinued but there are plenty of other options out there. There is a lot of latency but it works fine for entering chords into the PRV that I can edit afterwards.

I'm a guitar player and wanted to use the GR-55 as a midi instrument. I have an Akai MPKmini and that works great a midi instrument. Problem is, I suck as a keyboard player and thought it might be easier for me to use a midi instrument I was familiar with.

I'll try out the suggestions this weekend and see what happens.

Thank you again

You might want to try JamOrigin for guitar. It has a little lower latency than myGR 55, and I find I have less editing to do afterwards. I believe it can be demoed.
